The 2 GHz ceiling means this buffer can distribute high-speed reference clocks for SERDES, FPGA transceivers, or data-converter sampling clocks without adding jitter from a separate level translator. ## Supply rails and temperature grade The -40°C to +105°C operating range covers industrial equipment and base-station environments where the ambient temperature inside the enclosure can climb well above 85°C. The 1:2 fanout with differential input and output means the part can replace a discrete resistor-splitter network when driving two downstream loads from one source, preserving signal integrity at multi-gigahertz frequencies. ## Lifecycle and compliance RoHS compliance is standard for TI's VQFN packages in this family.","metaTitle":"Texas Instruments LMK1D2102RGTT Clock Buffer, 2 GHz","metaDescription":"Texas Instruments LMK1D2102RGTT clock buffer, 2 GHz max, 1:2 fanout, LVDS output.
